The chapter 12 begins with an introduction to Algebraic Expressions by citing some examples of algebraic expressions in one variable. Then the concept of how expressions are formed and terms of an expression are explained. Under this, the factors of a term and coefficients are discussed in detail. Then we have the discussion of like and unlike terms.
Monomials, Binomials, Trinomials and Polynomials are described in the next section. Addition and subtraction of algebraic expressions is explained in the following section. Then, we have the procedure to finding the value of an expression. The last topic of the chapter is formulas and rules in mathematics written in a concise and general form using algebraic expressions. Get the algebraic expressions in the following cases using variables, constants and arithmetic operations.
Let us first understand the meaning or definition of terms variable, constants Byjus Maths Class 7 Algebraic Expressions Model and arithmetic operations. Variables are the letters used in an algebraic expression that can take any value. For e. Constants always have fixed values in the algebraic expressions. They cannot be assumed or changed.
Arithmetic Operations are Addition, subtraction, multiplication and division. Show the terms and factors by tree diagrams. Identify the numerical coefficients of terms other than constants in the following expressions:.
This question is based on the concept of like terms. If there are same variable in all the terms in the expression, then the expression has like terms. We have to ignore constants here.
